Description
An account of the resource
Agricultural production systems have to combine management practices in order to sustain soil's profitability and quality. Organic farming is gaining worldwide acceptance and has been expanding at an annual rate of 20% in the last decade, accounting for over 24 million hectares worldwide. Organic practices avoid applications of synthetic fertilizers and pesticides, rely on organic inputs and recycling for nutrient supply, and emphasize cropping system design and biological processes for pest management, as defined by organic farming regulation in the world. In comparison with conventional farming, organic farming has potential benefits in improving food quality and safety. Plant production in organic farming mainly depends on nutrient release as a function of mineralization processes in soils. The build-up of a large and active soil microbial biomass is important pool of accessible nutrients, therefore, is an important priority in organic farming. In organic farming, there is positive effect of quantity and quality of inputs of organic residues on soil microbial biomass. In this way, the organic systems are extremely important for the increase of the soil fertility and the maintenance of the environmental sustainability.A produção agrícola tem de combinar práticas para prover a sustentabilidade do solo. A agricultura orgânica está ganhando aceitação mundial e cresce à taxa anual de 20% na última década, contabilizando mais de 24 milhões de hectares. As práticas orgânicas evitam o uso de fertilizantes sintéticos e pesticidas, enfatiza a aplicação de matéria orgânica, como também a reciclagem de nutrientes e de processos biológicos para manejo de pragas, através das regras dos sistemas orgânicos no mundo. Em comparação com a agricultura convencional, os sistemas orgânicos têm potencial de melhorar a qualidade e a segurança dos alimentos. A produção das plantas no sistema orgânico depende da liberação de nutrientes pelo processo de mineralização microbiana no solo. A construção de uma grande e ativa biomassa microbiana é um importante reservatório de nutrientes disponíveis. Dessa forma, isso é uma prioridade no sistema orgânico. Em sistemas orgânicos, há efeitos positivos da quantidade e da qualidade das fontes de carbono orgânico sobre a biomassa microbiana do solo. Nesse sentido, as práticas do sistema orgânico são extremamente importantes para o aumento da fertilidade do solo e para a manutenção da sustentabilidade ambiental.

Este trabalho tem como objetivo geral analisar como os agricultores familiares comportam-se frente às mudanças significativas no ambiente institucional da cadeia produtiva do leite a partir de novas legislações. Nesse sentido, foram investigadas as principais consequências e impactos na organização socioprodutiva das famílias produtoras de leite na região Oeste Catarinense em decorrência da Instituição Normativa n. 51 do Ministério da Agricultura. Para tanto, foi utilizada a abordagem da Nova Economia Institucional (NEI), especialmente no que tange à formação e adaptação dos agricultores ao ambiente institucional da cadeia leiteira. A metodologia utilizada foi o estudo de caso, e as informações analisadas foram obtidas através de pesquisa de campo junto a atores estratégicos envolvidos na produção de leite e derivados na região. Concluiu-se que a IN51 influencia decisivamente a forma de organização e participação da agricultura familiar na cadeia produtiva do leite.This paper aims to analyze how family farmers behave facing significant changes in the institutional environment of milk production chain. In this sense, we investigated main consequences and impacts on the social and productive organization of milk producing families as a result of the Institution Normative 51 by Ministry of Agriculture in the western region of Santa Catarina state. We used the approach of New Institutional Economics (NIE) and field research with strategic actors involved in the dairy production in the region. We concluded that the IN51 decisively influences the form of organization and participation of family farming in the milk production chain.

An account of the resource
O objetivo deste trabalho foi adaptar e testar uma metodologia participativa para promover e avaliar as mudanças de percepção e de atitude dos agricultores com relação às práticas de manejo sanitário da ordenha, através da construção e uso de indicadores que permitissem aos agricultores um processo de ação-avaliação constante. Foi realizado um estudo de caso em quatro Unidades de Produção Familiar (UPF), no município de Guaraciaba (SC), envolvidas na atividade leiteira. Após a caracterização das UPF e diagnóstico sanitário do rebanho, foi feita a construção participativa de indicadores de manejo sanitário de ordenha, a qual foi utilizada pelos agricultores ao longo de três meses para avaliação de suas práticas de manejo. Ao final desse período, foram realizadas entrevistas com as famílias participantes para apreender a sua percepção a respeito da metodologia empregada. Os agricultores avaliaram positivamente o uso da metodologia, destacando a melhoria de vários indicadores, devido às mudanças de atitudes. Destacaram também que a eficiência da metodologia se deve ao fato de ela proporcionar uma reflexão sobre aspectos reais da vida dos agricultores. Assim, a proposta metodológica participativa utilizada neste trabalho, dentro de uma perspectiva emancipadora, mostrou-se uma importante ferramenta de avaliação de sistemas, coerente com as premissas da Política Nacional de Assistência Técnica e Extensão Rural - PNATER.

An account of the resource
Este ensaio pretende discutir a aquisição de alimentos para o Programa Nacional de Alimentação Escolar à luz do seu marco legal vigente, na perspectiva de promover hábitos alimentares saudáveis e culturalmente articulados que contribuam para a promoção das condições de saúde da população escolar brasileira e para o desenvolvimento local. Apresentase análise da legislação em vigor do Programa Nacional de Alimentação Escolar, evidenciando a intencionalidade de influenciar o sistema alimentar brasileiro e o padrão alimentar de sua população a partir da alimentação escolar, destacandose as lacunas que desafiam a efetivação de mudanças substanciais na execução do programa. Partindo dessa análise e com base no elevado e crescente consumo de alimentos ultraprocessados no Brasil, e considerando as desvantagens desses alimentos diante de alimentos pouco ou não processados, desenvolvese proposta para orientar a construção de uma pauta de alimentos que seja consistente com o marco legal vigente do programa e com seus objetivos. Argumentase que a predominância de alimentos pouco ou não processados na alimentação escolar pode ser estratégia para o resgate do patrimônio alimentar saudável e para o fortalecimento do desenvolvimento local se resultar da aproximação com a agricultura familiar.

An account of the resource
Os insumos e serviços utilizados na produção vegetal representam custo energético. Dependendo desses fatores e das produtividades obtidas, a conversão da produção em energia determinará a eficiência energética do sistema. A agricultura orgânica somente atingirá a missão de preservação ambiental se tiver comprovada sustentabilidade energética. Neste trabalho, objetivou-se caracterizar os balanços energéticos dos cultivos orgânicos e analisar sua sustentabilidade, em comparação aos sistemas convencionais. Monitoraram-se campos de produção de dez culturas, de 1991 a 2000 em Domingos Martins-ES. Os dados do sistema convencional foram obtidos pelas médias dos coeficientes técnicos da região. Quantificaram-se os coeficientes técnicos, convertendo suas grandezas físicas em equivalentes energéticos, expressos em kcal. O sistema orgânico gastou 4.571.159 kcal ha-1 e apresentou 12.696.712 kcal ha-1 de energia inserida na colheita, mostrando balanço médio de 2,78. Esse valor foi similar ao obtido no sistema convencional (1,93). As participações dos componentes nos gastos do sistema orgânico foram embalagem (35,8%), composto orgânico (17,2%), irrigação (12,6%), sementes/mudas (12,4%) e mão-de-obra (11,0%), serviços mecânicos (5,0%) e frete (4,5%). Se os custos com embalagens fossem eliminados, os gastos do sistema orgânico seriam reduzidos para 2.930.113 kcal ha-1, aumentando sua eficiência. A maioria dos cultivos orgânicos pode ser considerada sustentável em transformação de energia, com balanços superiores a 1,00 e produção média diária de 80.421 kcal ha-1 por dia, superior à necessidade mínima de 58.064 kcal ha-1.The inputs used in crop production represent an energetic cost. Depending on the inputs and on the achieved yields, the conversion of the harvest into energy will determine the energetic efficiency of the system. Organic agriculture will fully meet the goal of environmental conservation only if its energetic sustainability is accomplished. The objectives of this study were to characterize the energetic balance of organic vegetable production and to analyze its energetic sustainability, compared to conventional vegetable crop production systems. Field data were collected from ten vegetable crop fields, from 1991 to 2000 in Domingos Martins, Espírito Santo State, Brazil. Data from the conventional system were obtained in the region. The technical coefficients of the systems were quantified and converted to an energy equivalent (kcal). The general average of the organic system was an input of 4,571,159 kcal ha-1 and an output of 12,696,712 kcal ha-1 at harvest, presenting an energetic balance of 2.78. This balance was similar to the conventional system (1,93). The components of the energetic inputs in the organic system were packaging (35,8%), organic compost (17,2%), irrigation (12,6%), seeds/seedlings (12,4%) and labor (11,0%), machinery (5,0%) and transport (4,5%). If package costs were removed, the energetic inputs on the organic system would be reduced to 2,930,113 kcal ha-1, greatly improving its energetic efficiency. Most of the crops could be considered sustainable regarding energy conversion, presenting balances higher than 1.00. The daily average energy yield in the organic system was 80,421 kcal ha-1 day-1 and was considered sustainable, higher than the minimum estimated calories need (58.064 kcal ha-1).

Sob manejo orgânico, foram avaliados, em Seropédica, RJ, os sistemas de plantio direto da berinjela (Solanum melongena) nas palhadas de Crotalaria juncea (crotalária), Pennisetum glaucum (milheto, cv. BRS 1501) e vegetação espontânea (pousio), em comparação com o plantio convencional (aração e gradagem ou enxada rotativa). Simultaneamente, foram avaliados três tipos de cultivo: berinjela em monocultura, em consórcio com crotalária e em consórcio com caupi (Vigna unguiculata, cv. Mauá). Não houve diferença entre os sistemas de plantio direto e convencional quanto à produção comercial da berinjela. A palhada da crotalária foi mais eficiente que a do milheto e do pousio para cobertura morta do solo e conseqüentemente o controle de plantas espontâneas foi maior. O cultivo simultâneo com as leguminosas não acarretou redução da produtividade da berinjela. Em um segundo estudo, foram comparados plantio direto (palhadas de crotalária e da vegetação espontânea) e plantio convencional, combinados com doses crescentes de cama de aviário (0, 100, 200 e 400 kg ha-1 de N) aplicada em cobertura. Em termos de aporte de biomassa, a crotalária foi novamente superior à vegetação espontânea. A berinjela respondeu à adubação orgânica, com produtividade máxima de 50,6 t ha-1 , correspondendo à maior dose empregada, contra 36,9 t ha-1 referentes ao controle.No-tillage systems were evaluated within an eggplant (Solanum melongena) organic management in Seropédica, Rio de Janeiro State. Crotalaria juncea and Pennisetum glaucum cv. BRS 1501 were used as pre-plantings besides fallowing, in comparison to conventional system (plowing). Simultaneously, three cropping managements were tested: eggplant single-cropping, intercropping with C. juncea, and intercropping with cowpea (Vigna unguiculata cv. Mauá). No differences were found among planting systems concerning eggplant yield. Crotalaria juncea was more effective than Pennisetum glaucum and fallow for soil mulch. Intercropping with leguminous species did not decrease eggplant yield. In a second study no-tillage (on C. juncea and spontaneous weeds mulchs) and conventional plowing were compared. These treatments were combined with increasing levels of poultry manure (0, 100, 200, and 400 kg ha-1 of N). In terms of biomass input, C. juncea was again superior to spontaneous weeds. Eggplant responded to organic fertilization with maximum productivity (50.6 t ha-1) corresponding to the highest manure level applied, compared to 36.9 t ha-1 for control plots.

El experimento se realizó en el Instituto Agrario de la Ciudad de Mocuba, Mozambique, usando un diseño de Bloques al azar con tres tratamientos (T0-sin fertilización, T1-Fertilizado con orina humana y T2-Fertilización química), y tres repeticiones, sobre un suelo arcilloso. Los resultados fueron sometidos a análisis de varianza del paquete Statistix 10.0 y las medias comparadas por la dócima de Tukey para una probabilidad de 5%. Las variables evaluadas fueron: altura de la planta (HP), diámetro de la mazorca sin paja (DM), largo de la mazorca (CM), peso de la mazorca (Pe) y rendimiento. Respecto a los tratamientos utilizados, los resultados del empleo de fertilizante orgánico a base de la orina humana resultó significativamente superior en los parámetros referentes la altura de la planta (HP) y diámetro de la mazorca (DM), sin diferencia significativa a respeto del tratamiento con químico (T2) en los parámetros largo de la mazorca (CM), peso de la mazorca (Pe) y rendimiento (R), que alcanzó en el caso de la orina humana 4.80 t/ha. Desde el punto de vista experimental, el presente estudio evidenció resultados promisorios acerca de la utilización de orina humana en la fertilización del maíz (Zea mays, L), indicando la posibilidad de su uso en la agricultura familiar reduciendo o sustituyendo el consumo de fertilizantes químicos. ABSTRACTTo test the effect of human urine on the yield of maize variety 'Matuba', conducted at the Institute of Agrarian of City Mocuba an essay using the randomized complete block design with three treatments (no fertilization T0, T1 fertilization with human urine and T2 chemical fertilization), and three replications in clay soil The data were interpreted by an analysis of variance package Statistix 10.0, the means were compared by Tukey test at 5% probability. The variables evaluated were: plant height (PH), ear diameter (DM), ear length (CS) ear weight g (PE) and yield (t/ha). Respect of the treatments tested, the application of human urine resulted in significantly higher parameters for plant height (PH) and diameter of the ear (DM), and no significant difference regarding the treatment with chemical fertilizer (T2) parameters ear length (CS), ear weight (PE) and ear (R), which reached in the case of human urine 4.80 t/ha. From the experimental point of view this study showed promising results on the use of human urine fertilization of corn (Zea mays L.) , indicating a potential application of human urine in agriculture in order to reduce consumption or even in some cases replace use of chemical fertilizers.

O objetivo deste trabalho foi avaliar quimicamente as fases sólida e líquida de biofertilizante suíno, separadas com diferentes floculantes. O delineamento experimental foi inteiramente casualizado, com cinco tipos de floculantes, sendo cinco doses de cadafloculante, com cinco repetições. A separação foi efetuada por meio defloculação/decantação por 1h após a adição do floculante. Realizou-se a caracterização química das fases sólida e líquida do biofertilizante, a partir da determinação de N, P, K, Ca, Mg, Cu, Zn, Fe e Mn. Na fase líquida, o objetivo de diminuir os macronutrientes foi atingido quando se utilizaram as doses 10 e 20 mL da combinação entre calcário dolomítico + hidróxido de cálcio, e os micronutrientes foram reduzidos quando foram utilizados os floculantes sulfato de alumínio e hidróxido de cálcio + sulfato de alumínio.The objective of this work was to chemically evaluate the solid liquid phases of swine biofertilizer separated by different flocculants. The experimental design was completely randomized, with five kinds of flocculants and five doses of each flocculant, with five repetitions. The separation was conducted through flocculation/decantation for an hour after the addition of each flocculent. The chemical characterization was done on the solid and liquid biofertilizer phases from the determination of the following elements: N, P, K, Ca, Mg, Cu, Zn, Fe and Mn. For the liquid phase, the purpose of decreasing macronutrients was achieved using the doses of 10 and 20 mL of the combination between the flocculants dolomitic limestone + calcium hydroxide, and micronutrients reduction occurred when the flocculants aluminum sulfate and calcium hydroxide + aluminum sulfate were used.

El mundo enfrenta la crisis del capitalismo el cual se dedica a despojar, robar y provocar guerras por los recursos naturales cada vez más escasos, mientras entre los grupos campesinos e indígenas se agrava la crisis ecológica y la problemática nutricional. Por lo tanto, la seguridad alimentaria es indispensable para la sobrevivencia y la equidad. En este marco, se investigaron los conocimientos tradicionales que conservan los habitantes sobre las plantas y animales alimentarios de los huertos tradicionales de la comunidad de Coatetelco, Morelos. Para sistematizar los saberes tradicionales vinculados a las plantas y animales alimentarios se efectuaron 34 entrevistas semi-estructuradas y se calculó la riqueza de conocimiento al respecto y la frecuencia relativa, se realizaron recorridos guiados para la colecta de las plantas y la observación de la fauna para su identificación mediante las claves correspondientes. Se registraron 60 especies de plantas y animales distribuidos en 38 familias, sobresaliendo la Fabaceae y Bovidae. Las seis especies con mayor importancia alimentaria fueron el limón Citrus aurantiifolia, papaya Carica papaya, guamúchil Pithecellobium dulce, gallina Gallus gallus, guajolote Meleagris gallopavo y la tórtola Columbina inca. El fruto se consume en una mayor proporción (69%), seguido de la carne (18%). Los huertos estudiados de Coatetelco proveen sosteniblemente alimentos y nutrimentos a las familias indígenas a lo largo del año. Por lo tanto, su conservación y manejo debe integrarse a las políticas públicas que garanticen el derecho a la alimentación nutritiva, suficiente y de calidad, y coadyuvar en este sentido a mitigar la pobreza alimentaria.
